Do you know what types of fastener seals are available? If it is not very clear, then take a look at this article! Fastener external thread clamp: common inner hole sealing. Its sealing ring is a triangular soft metal sealing ring made of copper or aluminum. The flange of the cylinder section is connected with the end cover of the container through the threaded sleeve, the compression bolt is tightened to apply force to the compression ring, and the compression gasket completes the sealing. Kazali seal inside the fastener: The principle of the thread Kazali seal is basically the same as that of the external thread, only the external thread end cover is indirectly screwed into the top of the cylinder with the thread. The sealing gasket is placed at the joint between the end cover and the tail end of the engine block, and the sealing gasket is equipped with a pressure ring. Fasteners——Improved Kazali seal: The improved Kazali inner hole seal structure does not use external thread sleeve specifications to connect the end cover and cylinder, but only uses screws to connect, and other parts are sealed with the external thread Kazali inner hole similar. It has no significant advantages, so it is difficult to choose. Fastener Flat Gasket Seal: This is also a mandatory seal. A sealing ring made of soft material or alloy is placed between the joint surfaces. Under the action of the pre-tightening force of the bolts, the uneven part (that is, the gap or hole where the substance may leak) is squeezed and filled with plastic deformation gasket material, so as to achieve the purpose of the container.
